SPECIFICATION forming part of Letters Patent No. 772,267, dated October11, 1904.

Application filed February 20, 1904. Serial VNO, 194,568. (No model.)

To @ZZ whom t weary concern.:

Be it known that I, CYRUS A. ARNSBERGER, a citizen of the United States,residing at Rudy, in the county of Fremontand State of Idaho, haveinvented a new and useful Pump, of which the following is aspecification.

My invention relates to duplex or balance pumps, such as are employedfor lifting water from a well or pool and discharging it at an elevatedpoint, and has for its objects to produce a simple efcient device ofthis character in which a practically continuous iiow of water will bemaintained through a single discharge-pipe common to and communicatingwith both of the pump-cylinders or standpipes.

To these ends the invention comprises the novel features of constructionand combination of parts more fully hereinafter described.

In the accompanying drawings, Figure lis a vertical sectional elevationof a pump embodying my invention. Fig. 2 is a detail sectional viewthrough one of the plunger-casings. Fig. 3 is a similar view showing thejoint between one of the vertical pipes and the horizontalconnecting-pipe.

Referring to the drawings, 1 designates a suitably-supported tank orreservoir, provided at its top with a discharge pipe or duct 2 and atits bottom with a depending tubular coupling pipe or duct 3, having aterminal ball or coupling head 4, upon which is centrally hung for freerocking movement a Walking-beam or other suitable operating member 5,provided with a socket 6 for the reception of the ball 4, and with alongitudinally-disposed channel or duct 7, communicating with the j duct3, for the purpose which will hereinafter appear.

Suspended respectively from opposite ends of the walking-beam 5 is apairof tubular stand-pipes or ducts 8, provided at their upper terminalswith coupling heads or balls 9, movement in suitable sockets formed-inthe wall of the walking-beam, said pipes being connected adjacent totheir lower ends for intercommunication by means of a suitableconnecting pipe or duct 10 and adapted to communicate at their upperends with the duct 7.

Connected respectively with the lower ends of the pipes 8 is a pair ofsubstantially circular casingsll. These casings, which are of similarconstruction, each has provided upon its interior a substantiallysemicircular plunger compartment or chamber 12, which communicates atits inner end through an opening 13 with a valve-chamber 14, into whichthe lower en'd of the adjacent pipe 8 is tapped, there being disposed inthe valve-chamber beneath the end of the pipe a freely-movableball-valve 15, designed to normally rest upon a suitable seat 16 forclosing the opening 13, while above the ball or valve there is arrangedan open-work guard or stop'17 to preventthe latter from rising suicentlyto close the lower end of the pipe 8.

Disposed respectively of the casings 11 for reciprocation within thechambers 12 is a pair of pump-plungers 18, which are connected foruniform and simultaneous movement by means of an element or web 19,preferably composed of a pair of sections carried, respec'` tively, bythe plungers and having their meeting ends detachably connected by boltsor otherwise. The plungers 18, which are identical in construction andoperation, are each preferably in the form of asubstantiallysegmental-shaped tubular body, pivoted for oscillation within its casingupon a pivoting pintle or axle 20, the peripheral walls of the casingbeing cut away or slotted at asuitable pointn to permit free relativemovement of the connecting element 19. Each plunger has a passage orduct 21 constantly open at its outer end to permit infiow of Water andprovided at its inner end with a suitable flapvalve 22,v which opensfreely upon the outstroke of the plunger to permit inflow of waterthrough the passage 21 to the chamber 12, but closes during theinstrolze of the plunger to prevent outiiow of the water through saidpassage.

The pivotal axle 2O for each plunger preferably consists of a pair ofoppositely-disposed and longitudinally-alined bolts tapped,respectively, into opposite sides of the casing 11 and provided at theirinner ymeeting ends with reduced portions or journals 23, seated in abearing-opening in the plunger. i

- In practice the walking-beam 5 .being operated 1n any suitable mannercausesa longitudinal reciprocation of the pipes 8, which of course areimmersed at their lower ends in the body of water to be acted upon. Asone pipe moves upward the other obviously travels downward, and thisalternate reciprocation of the pipes imparts the oscillatory orreciprocatory movement to the plungers 18 necessary for effecting thepumping operation. On the outstrolie of each of the plungers a charge ofwater is drawn into the adjacent chamber 12, and this charge is upon theinstroke of the plunger driven upward by the latter into the adjacentpipe 8, it being understood,of course,that the ball-valve 13 opensfreely to permit this upward passage of the water, but closesautomatically to prevent backfiow of the latter during the outstroke ofthe plunger. rfhus the water will belifted through the pipes 8 and ducts7 and 3 to the tank l, attention being here directed to the fact thatowing to the pipes 8 being connected by the pipe 10 less resistance isoffered to the upward passage of the water, thereby insuring apractically continuous delivery of water into the tank, from which itwill be discharged in a uniform stream.

From the foregoing it will be seen that I produce a simple eliicientdevice which is admirably adapted for the attainment of the ends inview; but itis to be understood thatI do not limit myself to the precisedetails'herein set forth, inasmuch as minor changes may be made withoutdeparting from the spirit of the invention.

Having thus described the invention, what is claimed isl. In a pump, thecombination with a walking-beam having a duct, of a pair of pipes car-lried by the beam for alternate reciprocation, said pipes being incommunication at their upper ends with the duct and provided at theirlower ends with plunger-chambers, a pair of plungers disposedrespectively for operation in the chambers and adapted on operation ofthe beam to alternately lift the water through their respective pipes.

2. In a pump, the combination with a walking-beam having a duct, of apair of pipes carried for alternate reciprocation by the beam and havingcommunication with the duct, and means operable by movements of thepipes for forcing water upward therethrough.

3. In a pump, the combination with a walking-beam having a duct, of apair of pipes adapted for alternate reciprocation by and inball-and-socket connection with the beam, said pipes being incommunication with the duct and provided with plunger-chambers, and apair of plungers disposed respectively in the chambers and connected forsimultaneous movement, said plungers being adapted to alternately liftthe water through their respective pipes as the latter reciprocate.

4. In a pump, the combination with a walking-beam having a duct, of apair of pipes carried for alternate reciprocation by the beam and havingcommunication with the duct, means operable by movements of the pipesfor forcing waterupwardly therethrough, and a duct connecting the pipesadjacent to their lower ends for intercommunication.

In testimony that I claim the foregoing as my ownY I have hereto affixedmy signature in the presenee of two witnesses.

CYRUS A. ARNSBERGER.
